.- i Be it known that I, FRANKLIN HASKINS, of Ware, in vthe county of Hampshire, and Commonwealth o f: Mas- 'sacli'usetts, liare'im'ented. nevi' ain'cl'improved Binder for Shuttle-Boxes ofv Looms; and that the following 'is a t'ull and exact description. thereof', reference being hud to theaecompanying drawings, mnkiga-partof this speeiiication, andtothe letters of vr'efernoca-'marked thereon, in ,Tillich-Q 'Figure l iso planietvof said binder.

Figure 6 is a. longitudinal vertical section through the line E F, vtig. 3.

VEigures 7.au`d 8 are-respectively a.A plan and elevation of the nut, through which the elevating-screw j passes; and

A' Figure 9 is a planet said elevating-screw. A v j v In theioperaton of looms, and especially of power-looms, the shuttle -containing the filling is moved along Y the' shuttleravce-or frane-bar" alternately from the shuttle-boi: at one'end of the race into the' corresponding shuttle-box ati the opposite end, and at ahigh rate of speed, being actuated by'thepiclcerlstis,orequivalent devices, Vwhich strike a sudden a'nd powerful blow upon the outer end of theshuttle at each side of the loom,

`and impart sufficient motion toit to propel it rapidly into' the opposite shuttle-boit.v The shuttle, 'so propelled,

will therefore have a considerable momentum when it enters 'the shuttle-box'and approaches .the opposite pickerst aii. To cheek this `momentum gradually, andsa'rrest themotion of the shuttle at-the proper pointto receive the return blow of the picker-staff, a shuttle-binder is generally placed upon or. in the side of each shuttle-box, I Vthe,operationoi' which binder is to gradually narroxv the width of the passage in which the shuttle is' moving,

'.-and'protluce more or less friction upon the shuttle until itfislbrought to :istruiti-still` "As the speed of'looms is' liablerto 'heehangedut anytime', so that the rete' of motionvofthe shuttle 'audits momentulwll be greater at z onre time'than another, it is desirable to vary the umountof4 friction or pressure exertedby thebinderupon'the shuttle, lso that the shuttle, whatever'its rate of speed'pfmay always be stopped at the contrepoint; and,'unl'ess1v .the binderkis cepbleiaffadjustment in this respect, itis evident' that the' shuttle, when driven'ata low speed, meyzbestopped tooianfronrth'e pickerstaii`,'a.nd, consequently, receive too week a blow from thezstaito drive y it bagkentirelyr'through the Warp, or, on the other hand, when driven at a. high speed, Vlrreystrilre the 'stai too violently-#in eitherrouse4 interfering Withthe proper and, snccessfuloperation of the loom. "Different sizes of Y shuttles also requirediierent adjustments of the .retarding friction.

The nature of my invention consists in the constructionbf a binding-attachment for the shuttle-boxesof looms, in two ports, oneV` offwhich is supported in or upon'theshuttle-hox, lend, in turn, supports the other'part, A

the `face of whichis curved and acts as a friction-piece, and has a longitudinel motion in'reference to'seidsupportingpart, 'and also a lateral I'hotion inthe direction of the width of thefflathe, being controlle d es ,.to both of these motions by thumb-screws. i i

The'object of the longitudincl'motion of the friction-piece 'iste apply thefriction to the sh'ul'e at a greater or less distance from the endio'f the shuttle-hex, `and the object of-,the'leteral motionis to make the friction so A Vapplied greater or lessil v `ihe construction o decreasing inthiclrnessfrom the rounded end. Aipin or :SG1-ew passing through theI openingginto somezpart of the simule-box, ats as t pivot, about-which A has t 'limited 11n-imm muon; Asma, is formed to anos; thcsteins of the tivo thumb-screws to traverse, and a shallow groove, n', which is rectangular in section, extends in the line of theslot ol, n sshown. Chzinnels c? e are also out on each side ofthe slot fpr a'. portion of Aits length, and at one endpto receive the sides off the nut b, and a small "ecess, d", is formeflet one endof said slot. TheV dimensions ofthe piece Awll vary Vith the size and purpose ofthe loom to'which it is to be applied, and the consequent strain upon the binder. A` y i i l I v yt'rny inventionpis as follows: The part is made of hard woodoi` a suitable width, andl The friction-piece B is made of. about the same width as'the supporting-piece A, and has upon its plane inner surface a projection or tongue, a, which islitted to enter the groove 2t', and guidesl the friction-piece in itslongfitudinal motion along the p iece The outer face is curved in the direction of its length, the outline shown being a compound curve, the lines Aot`l which will neecssarilj, be varied somewhat with the nature and operation of the1class of looms to which it is to be applied, with the shape of the shuttle used, and other rnodi fying causes, and will b e determined readily by the operator. To retain the friction-piece B in any position to whichit may be adjusted upon A, the head'c ofthe screw a is set firmly in the wood of tbc part B 4andcovercd by the piece Z.

If the friction-'piece be applied to A, as shown in figs. 1 and 2, and the nutf and washer applied upon e, the part B can be tightly clamped uponvA at any point in its longitudinal motion. A

To impart a lateral motion to B, the thumb-screw`a,turning in the nut b, is applied; The flanges c e on this nut, figs. 7 and 8, rest in the channels cc Iat the,sidcs of the slot d, and the end of the screw a works against a metallic plate, t,.{ig. 5, set in the wood'bclow the surface of B. As the screw a is turned inward, 4the end will press against the met-allie plate 7L, and tend to crowd one end of B away from A, the thumb-screw f being, of course, eased oil'.

Instead,tl1erei`o1e,'ot` removing binders, and substituting therefor others of dilfcrentform for different kinds of work 'or for different sizes of shuttles, I am enabled, by the arrangementdescribed, to canse the frictionpiecc B to project more or less into the shuttlc-bomtlrus serving the purpose of two or more binders of dilerent thickness, and also to bring the friction-piece in contaet with the 'shuttle at a longer or shorter distance fromthc-end of theshuttle-box. Y l

I prefer to construct the parts Av and of hard wood, b ut their relative operationwill be tlie'samc if .con-

i structed of metal, vulcanizedrubber, o'r other suitable material.

The operation ofmy invention is as follows: The friction-piece B-.is applied to A, sothat the tongue 1t enters the groove n', the Vwasher z' and nutf are applied to the screw 0,: and the screw a and nut Z1 are placed so that the end of .a will press against the plate L.. The binding-attachment is'thcn in readiness to be applied toA the shuttle-box, one at each end of the race` Binders are frequently inserted in a slot formed in the sidc of the shuttle-box, butimaybc attached in'any wayin which the proper contact of binder and shuttle may beobtained.

The outer end of each binder will be held iti yplace by 'the pin-oi` screw-through g, while the inner end will be controlled lby other connections not shown, andnot an essential part of this specification. rhe supportingr piece A being thus attached to the shuttle-box, the -frictionpiece B will have a longitudinal traverse along thci'ace et' A, the length of. which will depend upon the length of the slot d. i When the operator hasv ascertained by trial the precise point at which 4the frictionqpcce should moet the shuttle, he will adjust the latter accordingly, and to prevent it lfrom being loosened and displaced by the rapid blows of thevshuttle, the piece A is made thicker at the outer end, and acts as a tapering wedge, sov that the blows of theshuttle tend to clamp the friction-piece more closely to the part A, instead of loosening it. It' it Iis desirable to cause the friction-piece'to projectsfurther into 'the shuttle-box, it is accomplished by turning the thumb-screwa until the proper projection is obtained, alwaysveasing oil` the thumb-screwf suiiicicntly to'allow the end of B to be moved away from A The longitudinal and lateral adjustment being thus obtained, the friction-piece B is clamped lirmly in place by turning up the nutf. t' any further adjustment is found to lbe necessary, it may be readily and rapidly effected, without removing the binder from the shuttle-box, in vthe manner already described.`

I have also constructed the friction-piece of a strip of metal bent into a V-shape; and by cutting a screw. thread in the tongue, in which the screw a may turn instead of turning in the nut the other screw,`c, may hc dispensed with, and the thumb-screwf applied d irectlyto the `screw-thread a continued to the head of a, but I consider the same a. modification of my invention as described and shown. v

What I therefore claim as new, and desire' to secure by Letters Patent, isV

The tapering` supporting-piece A, in combination with the friction-piece B,' screws rl and e, and nuts I; and f, the whole arranged and operating substantially as described. l
